Kafka SASL 动物园管理员认证 [英] Kafka SASL zookeeper authentication

问题描述

我在 Zookeeper 和代理身份验证上启用 SASL 时遇到以下错误.

I am facing the following error while enabling SASL on Zookeeper and broker authentication.

JAAS文件中给出了如下配置，作为KAFKA_OPTS传入，作为JVM参数:-

Following configuration is given in the JAAS file, which is passed as KAFKA_OPTS to take it as JVM parameter:-

  KafkaServer {
       org.apache.kafka.common.security.plain.PlainLoginModule required
       username="admin"
       password="admin-secret"
       user_admin="admin-secret";
  };

  Client {
      org.apache.kafka.common.security.plain.PlainLoginModule required
      username="admin"
      password="admin-secret";
  };

kafka 代理的 server.properties 设置了以下额外字段:-

kafka broker's server.properties has following extra fields set:-

zookeeper.set.acl=true
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
ssl.client.auth=required
ssl.endpoint.identification.algorithm=HTTPS
ssl.keystore.location=path
ssl.keystore.password=anything
ssl.key.password=anything
ssl.truststore.location=path
ssl.truststore.password=anything

Zookeeper 属性如下:

Zookeeper properties are as follows:

 authProvider.1=org.apache.zookeeper.server.auth.DigestAuthenticationProvider
jaasLoginRenew=3600000
requireClientAuthScheme=sasl

推荐答案

我通过将日志级别提高到 DEBUG 来发现问题.基本上按照以下步骤操作.我不使用 SSL，但您可以毫无问题地集成它.

I found the issue by increasing the log level to DEBUG. Basically follow the steps below. I don't use SSL but you will integrate it without any issue.

以下是我的配置文件:

server.properties

security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN

authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
allow.everyone.if.no.acl.found=true
auto.create.topics.enable=false
broker.id=0
listeners=SASL_PLAINTEXT://localhost:9092
advertised.listeners=SASL_PLAINTEXT://localhost:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600

advertised.host.name=localhost
num.partitions=1
num.recovery.threads.per.data.dir=1
log.flush.interval.messages=30000000
log.flush.interval.ms=1800000
log.retention.minutes=30
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
delete.topic.enable=true
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
super.users=User:admin

zookeeper.properties

dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0
authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
requireClientAuthScheme=sasl
jaasLoginRenew=3600000

producer.properties

security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
bootstrap.servers=localhost:9092
compression.type=none

consumer.properties

security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
group.id=test-consumer-group

现在是让您的服务器顺利启动的最重要文件:

Now are the most important files for making your server starting without any issue:

zookeeper_jaas.conf

Server {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="admin-secret"
   user_admin="admin-secret";
};

kafka_server_jaas.conf

KafkaServer {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="admin-secret"
   user_admin="admin-secret";
};

Client {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="admin-secret";
};

完成所有这些配置后，在第一个终端窗口上:

After doing all these configuration, on a first terminal window:

终端 1(启动 Zookeeper 服务器)

来自 kafka 根目录

From kafka root directory

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/zookeeper_jaas.conf"
$ bin/zookeeper-server-start.sh config/zookeeper.properties

终端2(启动Kafka服务器)

来自 kafka 根目录

From kafka root directory

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/kafka_server_jaas.conf"
$ bin/kafka-server-start.sh config/server.properties

[开始更新]

kafka_client_jaas.conf

KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-secret";
};

终端 3(启动 Kafka 消费者)

在客户端，导出客户端 jaas conf 文件并启动消费者:

On a client terminal, export client jaas conf file and start consumer:

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/kafka_client_jaas.conf"
$ ./bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

Terminal 4(启动Kafka生产者)

如果您还想生成，请在另一个终端窗口中执行此操作:

If you also want to produce, do this on another terminal window:

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/kafka_client_jaas.conf"
$ ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties
